Almost all writing has a beginning (introduction), middle (body), and an end (the conclusion). Even when writing under a deadline, you should try to create all three components. Ignore the temptation to just start writing and hope you will make all the correct split-second decisions about what to say and where to include it. I know, I know – you’ve done it this way in the past and it has turned out okay. Trust me, a little time spent planning will more than pay you back in reduced test frenzy.
